Insert into instead of add to the HttpModules pipeline

Hello Noremac,
>
From your description, I understand you've developed a custom httpmodule
for providing SSO service in your ASP.NET web applications, you used to use
some simple configuration settings in application web.config file to
register your custom module, however, you found that you need much more
cofiguration elements in ASP.NET 2.0 application's web.config. So you're
wondering whether there is any more elegant means to do this, correct?
>
Based on my research, ASP.NET 2.0 has added many new built-in httpmodules,
and the "RoleManager" module is a new module which also related to forms
authentication and authorization. You can try reordering all the following
modules(put after your custom module) in application's web.config file to
see whether it helps:
>
"FormsAuthentication"
"RoleManager"
"UrlAuthorization"
>
>
Also, in .NET 2.0, it provide a set of configuration API that can help us
manage the application(or machine level) configuration in code. For
example, here is a test page which use web configuration API to insert a
custom httpModule before the "FormsAuthentication" module:

================
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Response.Write("<br/>current user: " + Environment.UserName);
>
}
protected void btnButton_Click(object sender, EventArgs e)
{
Configuration config =
WebConfigurationManager.OpenWebConfiguration(Reque st.ApplicationPath);
>
HttpModulesSection section =
config.SectionGroups["system.web"].Sections["httpModules"] as
HttpModulesSection;
>
if (section != null)
{
Response.Write("<br/>section: " + section);
>
ConfigurationElement[] modules = new
ConfigurationElement[section.Modules.Count];
section.Modules.CopyTo(modules, 0);
>
List<ConfigurationElementnewmodules = new
List<ConfigurationElement>();
>
foreach (ConfigurationElement elm in modules)
{
Response.Write("<br/>" +
elm.ElementInformation.Properties["name"].Value);
>
if (elm.ElementInformation.Properties["name"].Value.Equals(
"FormsAuthentication"))
{
Response.Write("<br/>insert my module here");
HttpModuleAction mymodule = new
HttpModuleAction("mymodule", "simpleModule");
>
newmodules.Add(mymodule);
>
}
>
newmodules.Add(elm);
}
>
>
section.Modules.Clear();
>
>
foreach (ConfigurationElement elm in newmodules)
{
Response.Write("<br/>new module: " +
elm.ElementInformation.Properties["name"].Value);
section.Modules.Add((HttpModuleAction)elm);
}
>
config.Save(ConfigurationSaveMode.Modified);
>

}

}
}

Here are some MSDN reference introducing the new web configuration API:
